1) What changes should I do as background image to be from side to side of screen just like in demo. To me, in this moment, image start from the right side but remains a space of a few pixels to the left of the screen.
2) I would like to use my own text like in demo, with title and description on background image. I put text in the "title", "description" and "into text" fields. All this appear less title in front-end.
